Hi all,
This is my problem.
When you turn on the power, ethernet lights are fixed, but three / four seconds off. Dreambox 800 starts fine, but internet does not work (attached photo)

I measured the volt as explanation and these are the results (attached photo)

I'm measuring correctly?

What else can I check?

Thanks

Yes it seems that you measure it correctly.

But if you have,
Network, same symptom, with or without network cable both network leds on, then off.
But the L5 inductor and caps are fine..
*When you check the serial port with a terminal program as Hyperterminal or Putty, and you receive garbage.
Replace the Crystal Y1 54.000.

Replace the u17 rs232 ic and probably also the crystal Y1 54.000.

This looks strange to me,

Code:
SW != 9000
error in receive
error during t1 transfer
SW != 9000
error in receive
error during t1 transfer
SW != 9000
error in receive
error during t1 transfer


Like if the sim was not communicating properly or was defective. Can you try with another sim ?

If you press the frontpanel button to load an image, connected with the RJ45... how does the box react and shows on Frontpanel LCD ?

Just as example of a working Sim, you need to all all details as on attachments, and not a MAC that is FF:FF:FF:FF:FF:FF:FF:FF.

Code:
WARNING: read invalid MAC address ff:ff:ff:ff:ff:ff from flash @ 0xbffff824


Thank you,

Admin

Based on that you get a normal terminal output, and no boot issues.
Then there is no reason to replace the crystal.

Maybe you need to reset your bios to fabric standard.
But, there are also other reasons why the network fails, even the connector could be the reason.

Se for all the information I have here..

Thanks for your help,
Clicking on the display only appears ** *** STOP ...

Entering the bios with putty, this is what appears
http://subefotos.com/ver/?0300bfe7a7c46fbf3eaa87f2ca3335a1o.jpg

Which option is to do a reset?

Johnny B where start checking the possible failure?

Your Kernel command line is a bit strange, it should be someting as,
console=ttyS0,115200 root=/dev/mtdblock3 rootfstype=jffs2 rw

Reset question, see tab Exit, and Factory default.

The Kernel command line should change to,
console=ttyS0,115200 root=/dev/mtdblock3 rootfstype=jffs2 rw
After you have reset the bios to the Factory default.

If not, copy & paste this command line, and save and exit.
Check it after a reboot, if it's still this normal command line.
console=ttyS0,115200 root=/dev/mtdblock3 rootfstype=jffs2 rw

Because yours is wrong, and could be your network issue.
